Dishwasher not draining completely

You have to pull the dishwasher out from underneath the counter and set it on its side. Before removing, I used a shop vac to remove any standing water from inside the dishwasher. Once I pulled out the dishwasher, I then tilted the dishwasher forward to let remaining water fall on the floor, again, using the wet vac for clean up. After it is on its side, I used a socket wrench to remove the one bolt that holds the drain valve on. Then I used a socket wrench to loosen the clamp for the drain hose and removed the hose. You then need to turn the entire drain valve 1/4 of a turn counter-clockwise to remove the old drain valve. Once it is off, remove the bracket from the old drain and attach it to the new drain valve using a phillips screwdriver. Before I reassambled the drain valve, I used my wet vac to remove any debree from where the drain valve connects to the dishwasher. Reverse the prior steps to install new drain valve and install dishwasher back under the counter. I tested the unit before installing the dishwasher back under the counter to insure it fixed the problem. The hardest part about doing this, was actually taking the dishwasher out from under the counter, very easy process in general. One thing I couldn't figure out about my original problem of the water not completely draining out, is why would the drain valve start draining the water then after 20 seconds it would stop? I couldn't find the answer, so I assumed the drain valve is like a 2 stage system and took a chance on replacing the drain valve; it worked.

I ordered and replaced both the door gasket (easy) and inner door seal (difficult) to try and correct a leak during operation. The door gasket was easily replaced. However, the inner door seal was a bit more trouble. After removing the inner door I found that the old inner seal needed to be removed and surfaces thoroughly cleaned of old build-up of dishwasher soap residue, in order to allow the sticky back tape side of door seal to properly stick to the door. There also was a plastic cover over the wire bundle that needed to be cleaned. The inner door seal was the exact length, so proper positioning of the sticky back was very important. Upon reassemly the leak still existed and I was unable to correct the leak. Further inspection indicated that the basic tub/body of the dishwasher might be slightly distorted due to age and may not create seal with door seal as originally designed. I guess I need to find a new dishwasher, at this point.A word to the wise: Check to see if the tub/body is still in good condition.

Remove the racks top and bottom. The Station D seals are at the far back on the tube that supplies water to the top and middle spray heads. Unsnap the old one and snap in the new - it only goes one way! This will repair the seal aroound the tube that supplies the middle sprayer and restore pressure to all 3 heads. Repalcing the screen accumulator is harder. you need a torx driver. remove the little thumb nut on the bottom sprayer and remove the sprayer. Then remove the tube where you just replaced the D station. (You of course could have done this earlier if you were doing both repairs) then 6 screws on the impeller housing. Now remove the 1 torx screw on the impeller and pull the impeller up and off. Remove the 3 screws on the cover and 2 screws on the accumulator. Clean all the old food scraps that are clogging up the works and reassemble in reverse order. Washer is working again!!

A storm power surge "fried" the main circuit board

I separated the door from the interior door liner by unscrewing the "torx" screws along the edge of the door interior (about 12 screws). I unscrewed the circuit board cover and removed the old circuit board and disconnected the wiring harnesses that attached to the circuit board. I reconnected the wiring harnesses to the new circuit board, put the circuit board back into its holder and cover and reattached the door liner to the door. I flipped the house circuit breaker for the dishwasher power on and turned the dishwasher on. It works like a charm!

Wash motor not pumping and making a grinding sound

I went to PartSelect and found the parts pictorial. A replacement motor was listed for 3 series of the dishwasher. The series can be identified by the first 2 digits of the dishwasher serial number. Mine was 22 so I needed parts for the series 20 dishwasher.

According to the pictorial it looked like the motor seals were included with the replacement motor. When the motor arrived, I found the seals were not included. I called PartSelect and they shipped the seals to me with free overnight delivery.

I had no trouble disassembling the wash manifold and spray parts using the instructions provided with the replacement motor and the instructions from the Maytag repair manual that I found online. The motor is removed from the inside of the tub.... very nice. You don't need to remove the dishwasher from under the counter in order to get at the motor.

I made a mental note of the orientation of the faulty motor before I removed it. I installed the replacement motor with the same orientation along with the wash parts. The dishwasher worked successfully.

Thank you PartSelect.

leak in front right corner

I had to remove the 4 screws holding the toe panel. Then I had to take out the one screw holding the floater switch housing in place. It snapped open to release the floater and that just lifted out. I put the new float in and snapped the new housing on. I put the screw back in to hold the housing in place attached the two wires to the switch and put the toe panel back on. It was all very easy to do and my first home repair went very well. thank you.

Dishes were coming out dirty with specs of debris on them

I noticed there was a filter type of material in the bottom of the dishwasher that had a small tear in it and figured that was my problem. I removed the nut from the sprayer arm at the bottom of the tub, removed the sprayer arm, removed 3 screws of the plastic cover below that. Removed six screws on the plastic cover below that. Removed one screw fron the center of the black pump spinner wheel that allowed me to lift off that cover. Then I lifted out the flowplate assembly. Placed the new part in and reversed the steps. Works like new again! All for about $30...I am not trianed in any way and have no experience in this kind of thing but am motivated trying to avoid a large service bill for a few screws. I am so happy...Thanks PartSelect!

Dishwasher would fill properly but when wash cycle would start you could not hear any water spraying.

First I removed the lower spray arm by removing the middle retainer nut. Next remove the 3 screws holding the outer shroud in place. Next remove 6 screws holding the water pump top housing in place. Under this housing you will find the impeller which is retained by a screw. Check the impeller closely for cracks especially near the center hex portion of the impeller. Replace if you have any doubt of it's integrity. Next remove the lower pump housing that has the screen material in the center. What I found was the nylon part that attaches to the shaft of the motor was stripped so the impeller would spin in it's normal direction ( counterclockwise) but under the load of water it would not. So I ordered a new impeller and seal kit with a metal sleeve and chooper blade. Follow the instructions provided in the new kit a reassemble accordingly.

Would not spray.

Looks like Maytag knew this was a problem. My chopper sleeve (plastic) was stripped and causing the impeller to not spin. The replacement part was all metal and was very easy to replace the old one just by removing screws. The replacement looks to be very sturdy and should last a lot longer than the original. Thanks.

Leaking at bottom of door

The initial repair was more involved due to figuring out how to get at the problem. A foam sealer strip located at the bottom of the inner door had lost it's seal. I first sent off for one and it was of relatively thin material. It was carefully installed but still leaked. I ordered another one from Part Select and it had thicker foam. It was installed right over the previously installed strip and made a tight seal. (knock on wood)

Dishwasher wouldn't stay on without pushing on door due to faulty switch.

This switch was not the correct one initially as it was a normally closed switch, whereas the existing switch was a normally open. Was able to pry open the switch and switch the contacts to normally open so it worked out in the end. Would recommend purchasing the complete latch assembly w/ switches if you aren't comfortable taking the switch apart.
